Basilar artery aneurysm is an abnormal localized widening or ballooning of the wall of the basilar artery. Sometimes, this aneurysm puts a great stress on the artery wall and cause it to burst. Before the aneurysm bursts, symptoms include a sudden and unusually severe headache, nausea, vision impairment, vomiting, and loss of consciousness, or the individual may experience no symptoms at all. When the basilar artery aneurysm ruptures, it usually results in bleeding into the meninges or the brain itself, leading to a subarachnoid hemorrhage (SAH) or intracranial hematoma (ICH), either of which constitutes a stroke, which can cause the death or paralysis. Aneurysm of the basilar artery can be corrected with a basilar artery angioplasty.
